UNITED STATES PATENT 4OEEICE.

JACOB DUNTON, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVED CAN OR BOTTLE STOPPER'.

Specification forming part of Letters Patent No. 37,221, datedDecember23, 1862.

T0 @ZZ whom, it may concern:

Be it known that I, J AcOB DUNTON, ofthe city and county ofPhiladelphia, in the State of Pennsylvania, have invented a new andImprovedBottle or Can Stopper; and I do hereby declare the following tobe a full and exact description of the same, reference being had to theaccompanying drawings, making part of this specification, in which-Figurel represents in perspective the various parts of the said stopperdetached from one another. Figs. 2 and 3 are detail sections of thestopper complete'under two modications.

Similar letters of reference indicate corresponding parts in both views.

The subject of my invention is a stopper especially intended formedicine bottles and jars, and consisting of a plain cylindrical pieceof cork fitting within a metal socket, which is formed with a milledhead and an external thread to adapt it to be screwed into a metal neck,which latter is formed with an internal iiange affording an extendedbearing for the cork, as will be hereinafter more fully explained.

To enable others skilled in the art to which my invention appcrtains tofully understand and use the same, I will proceed to describe itsconstruction and operation.

A represents a metal socket, the interior of which may be cylindrical ortapered slightly downward and formed with a slight shoulder, a. Ascrew-thread is formed upon the eXterior of the socket A at c,

B is a milled head attached to and covering` the socket, and extending asufficient distancel beyond it for convenience in screwing andunscrewing the stopper.

C represents a cylindrical plug of cork or other elastic material,which, when suitably compressed, is forced into the socket A, where itis firmly held by the form of the socket and the shoulder a.

D represents a metal neck, which may be attached to or form part of abottle or jar of` any suitable construction. The said neck is formedwith an internal screw-thread at d, to receive the thread c upon theexterior of the socket A, and with an inwardly-projecting annulariiange, E, which constitutes a seat or bearing for the cork C.

In the center of the annular flange E is the aperture F, through whichthe bottle is filled or emptied.

G represents a lip or iiange projecting out ward from the margin oftheneck D, in order to enable the dropping or pouring of liquidsaccurately in any quantities desired.

The metal socket and neck may be made of any suitable alloy which may bebest adapted to resist the action of acids and other substances whichthe bottles are required' to contain.

Among the advantages of the invention may be mentioned its simplicity,cheapness, eii.- ciency, and durability. It is superior to someanalogous devices in admitting of the use of a plain cylindrical pieceof cork of common form, instead of requiring it to be of special orpeculiar construction, and when screwed down the cork has a large andeven bearing, affording complete security without abrasion ordistortion.

For closing bottles, as illustrated in Fig. 3, the neck D may, ifpreferred, be made of glass in One piece with the bottle.

I do not desire to restrict myself to any pai ticular material in themanufacture ofthe stopper. It may be made of metal, hard rubber, or anysuitable substance or compound.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

A bottle or can stopper consisting ofthe socket A, formed with a milledhead, B, external screw-thread, a, and internal shoulder, a', the neckD, formed with an external lip, G, internal screw-thread,d, and annularflange E, and the imperforate cylindrical cork or plug G, allconstructed, combined7 and arranged in the manner and for the purposesshown and described.

JACOB DUNTON.
